Description

【0001】
【発明の属する技術分野】
本発明は水洗便器に関し、洗浄水に洗剤等を混入し便器洗浄を行う形式の水洗便器に関する。
【0002】
【従来の技術】
従来、ポンプを用いて洗浄水の圧力を高め、この圧力水を縮流孔に通すことにより流速を高め、この運動エネルギーを使って石鹸等の原液を吸い込ませ、さらに圧力水と石鹸原液は混合され混合液となり下流の拡径した空間に噴出されることにより、拡径した空間に設けられた空気孔から空気が巻き込まれ、混合液はさらに下流に設置されている網体に衝突することで泡が生成され、さらに下流にも網体が設けられ一部が衝突してさらに良好に空気を混入して良好な泡を生成され外部に吐出されるものであった(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特開平8−302796号公報(第2−4、第1図)
【0004】
【発明が解決しようとする課題】
上記従来の構成においては、巻き込んだ空気と混合液を網体を用いて泡としているが、網体に薄められた石鹸が付着することによる目詰まりが発生する。また網体がなければ空気を均一に混合液中に泡として生成することはできない。さらには、縮流孔において圧力水と石鹸原液を混合するため縮流孔においても目詰まりが発生しやすい構成となっている。
そこで、本発明においては網体を用いることなく吸引した空気を混合水に均一に泡として生成させると共に、縮流孔で石鹸原液等を吸い込むのではない構成を持ち、石鹸原液等が詰まることのない水洗便器の洗浄水噴出装置を提供することを目的とする。
【0005】
【課題を解決するための手段および作用・効果】
上記課題を解決するための請求項1記載の水洗便器は、洗浄水の供給を制御する開閉弁と、この開閉弁に連通する洗浄水給水口と、前記洗浄水給水口の下流に配置され、同一円周上に複数配置された洗浄水を噴出する洗浄水噴出口を有する洗浄水噴出ノズルと、空気を導入する空気導入口と、洗剤原液等を入れた洗剤タンクと前記洗剤タンクと連通する吸込口と、前記洗剤タンクからの吸込みを制御する吸込み用開閉弁と、前記洗浄水噴出口の下流に設置され、噴出した洗浄水と空気と洗剤を接触させ混合させるための混合室と、前記混合室の下流に設けられた洗浄水を衝突、滞留させるための流路内側へ突出した段部と、段部より下流に設置され空気と洗剤と混合された洗浄水を放出する大気開口した洗浄水吐出口とを有し、前記空気導入口と前記吸込口は前記洗浄水噴出口より下流の前記混合室に設けられていることを特徴とする。
【0006】
本発明においては、洗浄水噴出口で供給された洗浄水の圧力エネルギーを運動エネルギーに変換し、洗浄水噴出口から吐出した洗浄水の流速を高めることで混合室において空気及び洗剤タンクから洗剤原液等を巻き込む。巻き込まれた空気及び洗剤は、混合室下流に設けられた段部に衝突し、滞留することで激しく混合され均一となり、洗浄水吐出口から外部に吐出される。本構成では、段部により空気及び洗剤を均一に混合させるため網体等を用いることがないため目詰まり等の恐れがない。さらには、洗剤原液等の吸込口を洗浄水噴出口より下流の混合室に設けているため、巻き込まれた洗剤により洗浄水噴出口が目詰まりすることがない。さらには、洗剤と空気を同時に巻き込むため、洗剤の泡立性が増すことで、洗浄力が向上する。
【0007】
請求項2記載の発明は、空気導入口に空気を導くための空気ポンプと、空気ポンプと空気導入口を連通する空気流路とを有することを特徴とする。
本発明においては、洗浄水に巻き込まれる空気を空気ポンプで供給するため洗浄水供給手段の水圧条件の関わらず安定して空気を供給できる。また、洗浄水噴出口からの運動エネルギーを洗剤原液等の吸い込みだけに使うことができるため、より多くの洗剤を吸い込むことができる。
【0008】
請求項3記載の発明は、空気導入口の口径は吸込口の口径よりも小さいことを特徴する。
本発明においては、空気導入口の口径を吸込口の口径よりも小さくしたため、空気より
洗剤原液等を優先的に供給できる。このことにより、濃度の高い洗剤での洗浄が可能となる。
【0009】
請求項4記載の発明は、空気導入口は吸込口よりも下流に設けられていることを特徴とする。
本発明においては、空気導入口を吸込口よりも下流に設けたため、空気より洗剤原液等を優先的に供給できる。このことにより、濃度の高い洗剤での洗浄が可能となる。
【0010】
請求項5記載の発明は、洗浄水噴出口は洗浄水噴出口からの吐水同士が直接衝突するよう内向きに開口していることを特徴とする。
本発明においては、洗浄水噴出口を内向きに開口させ洗浄水噴出口からの吐水同士が
激しく衝突し、攪拌される構成としたため、空気の巻き込み量及び洗剤の吸込み量が増加する。さらには、洗浄水噴出口からの吐水が空気導入口及び吸込口から離れているため吐水が空気導入口及び吸込口を塞ぐことがなくなるため、安定した供給が可能となる。
【0011】
請求項6記載の発明は、吸込口は前記混合室の中心を通る水平面より上方に設けられていることを特徴とする。
本発明においては、吸込口は略水平よりも上方に設けられているため、吸込口が混合室内に溜まった混合水で塞がれることがなく洗剤を安定して吸い込むことができる。
【0012】
請求項7記載の発明は、洗浄水を溜水として貯留するボール部を有する便器本体において、ボール部内壁面の上縁部に沿って略水平に吐出しボール内壁面に沿って旋回させるよう設置されたことを特徴とする。
本発明においては、溜水の静止界面よりも上方のボウル部内壁面に沿って略水平に泡立った洗剤を含んだ洗浄水が吐水され、ボウル部内壁面上を周回しつつ、ボウル部内壁面を洗浄する。洗浄水はボウル部内壁面に滞留する時間が長く、洗剤も含まれているため高い洗浄力をもつことができる。さらに、溜水面は洗剤の泡で満たされることにより汚物落下によるおつりの防止にも効果的である。
【0013】
請求項8記載の発明は、洗浄水を供給するための開閉弁を開弁させた状態で、一定時間遅れて吸込み用開閉弁を開弁し、その後ある時間間隔をおいて吸込み用開閉弁を閉弁した後、一定時間経過後、開閉弁を閉弁するモードを有することを特徴とする。
本発明においては、開閉弁を開弁し洗浄水を吐水したのち一定時間遅れて吸込み用開閉弁を開弁することにより、ボウル面内壁面を濡らした状態で洗剤を含んだ洗浄水を吐水することで洗浄水のすべりを良くし周回しやすくするとともに隅々まで広がり、十分洗浄水が行きわたることにより洗浄力が向上する。
さらに、吸込み開閉弁を閉弁後ある時間間隔をおいて開閉弁を閉弁することにより、ボウル面内壁面に付着残留した洗剤を含む泡を洗剤を含まない洗浄水で完全に溜水に落として便器洗浄を行なうことができる。
【0014】
請求項9記載の発明は、洗浄水を供給するための開閉弁を開弁させた状態で、一定時間遅れて吸込み用開閉弁を開弁し、その後同時に閉弁するモードを有することを特徴とする。
本発明においては、開閉弁を開弁させた状態でまず、洗浄水を吐水するためボウル内壁面を濡らした状態でその後一定時間吸込み用開閉弁を開弁した後閉弁するお掃除モードを設けることで、ブラシ等を使った十分な洗浄を行なうことができる。また、別途洗剤を持ってくる手間もなくなる。
【0015】
【発明の実施の形態】
本発明の一実施例について説明する。図1に示すように、水洗式大便器本体1は、溜水を貯留するボウル部2と、一端がボウル部2の底部に連通し、他端が図示しない外部排出管に接続したリバースタイプのSトラップ3と、ボウル部2の後方にバルブユニット6及び洗剤タンク9を収納した機器収納部5を備えている。バルブユニット6は止水栓11を介して水道配管12に接続する給水配管10に接続している。洗剤タンク9は、洗剤の吸込みを制御するための吸込み用開閉弁29と連通チューブ28を介して泡生成装置7に接続されている。また、水洗式大便器本体1の側面には、洗剤タンクへの洗剤液の補給が容易に行なえるよう洗剤液補給口9aが設けられている。
【0016】
図2に図1のA断面を示す。ボウル部2内壁面の上端周縁には、上部が内周側に張り出したオーバーハング部4を形成している。また、ボウル部2内の溜水の静止界面よりも上方に、且つオーバーハング4の直下には、ボウル部2の内壁に大気開口した泡生成装置7の洗浄水吐出口31を備えている。
再び図1の戻り、泡生成装置7はバルブユニット6に給水路14を介して接続されている。
機能収納部5内に収納されているバルブユニット6の内部には、上流から給水配管10に接続した電動バルブ61と、定流量弁62と、内部接続管63を備えており、電動バルブ61は便器洗浄操作を支持するための操作装置64と連動している。
【0017】
泡生成装置7は、図3に示すようにバルブユニット6の内部配管63に連通する給水路14に接続された洗浄水給水口22と、洗浄水給水口22の下流に洗浄水流路を塞いで配置され、同一円周上に複数配置された洗浄水を噴出するため洗浄水噴出口23を有する洗浄水噴出ノズル24と、洗浄水噴出ノズル24の下流に設けられた混合室25と、洗剤タンク9内の洗剤を混合室25に導入するために混合室25の周壁25aに設けられた吸込口26と、混合室25の周壁25aに設けられた混合室25に空気を導入するために大気開放された空気導入口27と、混合室25の下流に設けられ洗浄水噴出口23からの水流と混合室25内の巻き込まれた空気及び洗剤液が衝突し、滞留するための段部30と、段部30よりも下流に設置され空気と洗剤液とを均一に混合した洗浄水を放出するための大気開放した洗浄水吐出口31とから構成されている。
【0018】
本実施例に係る泡生成装置7を含む水洗式大便器の動作を説明する。
便器使用者が操作装置64を操作して便器洗浄を指示すると、バルブユニット6の電動バルブ61が駆動し、水道配管12から水道圧力によって圧送された洗浄水が定流量弁62でその流量を所定量に調整され、内部接続管63、給水路14を通って洗浄水接続口22へ流入する。
洗浄水接続口22へ流入した洗浄水は、洗浄水噴出口23で内向きに混合室25の略中心軸に向かって加速され、噴出直後に衝突する。衝突した洗浄水は略中心軸に沿って流れる水流と周辺に分散する水流に分かれ、分散した水流は空気との接触面積が非常に大きくなり、せん断力よって大気開放された空気導入口27から多量の空気を巻き込むとともに、便器洗浄操作と連動して開いた吸込み用開閉弁29、連通チューブ28、吸込口26を通して洗剤タンク9からエジェクター効果により洗剤液を吸い込む。洗浄水は巻き込んだ空気と洗剤液とともに混合室25の下流側に飛散しながら流れていく。
【0019】
分散した水流は混合室25の内壁面に衝突しながら段部30に衝突して粉砕し、粉砕した洗浄水の一部は混合室25の上流側に反射し、段部30周辺に一時的に滞留する滞留水となる。滞留水中に勢いよく進入する混合室25の略中心軸に沿った流れによって、混合室25で巻き込んだ空気と洗剤液を滞留水中に混入することができる。混入した空気と洗剤液とから成る泡と滞留水にさらに上流から略中心軸に沿った流れが衝突すると、混入した空気と洗剤液から成る泡は水流のせん断力によって破砕されるため、細分化され洗浄水中に安定した泡を含んだ吐出流を生成できる。
【0020】
段部30は洗浄水噴出口23から噴出し、混合室25の略中心軸で衝突し、混合室25の内壁面に衝突した流れがバランスよく一時的に滞留するように設定されている。
段部30より下流の吐出路31aが直管で形成されているため、洗浄水中に安定した泡を含んだ流れは、乱れの少ない整流された流れとなり洗浄水吐出口31からボウル部2内へ吐出される。
洗浄水吐出口31から吐出された泡を含んだ洗浄水は、溜水の静止界面よりも上方のボウル部2の内壁に沿って略水平に吐出される。泡を含んだ洗浄水は、ボウル部2の内壁面上を周回しつつ、ボウル部2内壁面を洗浄する。ボウル部2内壁面は洗剤液を含んだ速い流れで、しかも気泡を含んだ流れであるため泡立性もよく、強力に洗浄される。
【0021】
図4は水洗便器の洗浄水吐出装置の洗浄シーケンスの一実施例について説明する。便器使用者が操作装置64を操作して便器洗浄を指示すると、バルブユニット6の電動バルブ61が駆動し、水道配管12から水道圧力によって圧送された洗浄水が定流量弁62でその流量を所定量に調整され、内部接続管63、給水路14を通って洗浄水接続口22へ流入する。泡生成装置7において、気泡を含んだ気泡流となり、洗浄水吐出口31より吐出される。吐出された気泡を含んだ洗浄水は溜水の静止界面より上方のボウル部2の内壁面に沿って略水平に吐出され、内壁面上を周回しつつボウル部2内壁面を洗浄する。電動バルブ61の開弁から一定時間T1遅れて吸込み用開閉弁29が開弁され、気泡流に洗剤液を含んだ洗浄水が洗浄水吐出口31からボウル面2の内壁面に略水平に吐出される。ボウル面2の内壁面は気泡流で濡れた状態であり、そこに洗剤液を含んだ洗浄水を流すことで、洗剤液を含む洗浄水のすべりを良くし、周回しやすくするとともに隅々まで広がるとことで広範囲にわたって十分洗浄することができる。その後一定時間t2経過後、吸込み用開閉弁29を閉弁し気泡流を含んだ洗浄水のみを吐出し、ボウル面2の内壁面に残った一部の洗剤の泡を溜水内に導くことで、洗剤残りをなくす。その後電動バルブ61内の流路を切替え、ジェット給水路15、ジェット吐出口13からボウル部2内へ洗浄水吐出が所定時間継続すると、Sトラップ3が汚水で満たされ、サイホン現象が発生する。サイホン現象により、ボウル部2内の汚水が一気にSトラップ3を介して、外部排出管へ排出される。Sトラップの空気吸い込みによりサイホン現象が終了すると、電動バルブ61の流路が再び切り替わり、泡生成装置7の洗浄水吐出口31からボウル面2の内壁面に沿って気泡流洗浄水吐出が所定時間t4継続すると、電動バルブ61が閉弁し、洗浄が終了する。
【0022】
図5は水洗便器の洗浄水吐出装置の洗浄シーケンスの別の一実施例について説明する。
本洗浄シーケンスでは、便器使用者が操作装置64を操作して便器洗浄を指示すると、バルブユニット6の電動バルブ61が駆動し、水道配管12から水道圧力によって圧送された洗浄水が定流量弁62でその流量を所定量に調整され、内部接続管63、給水路14を通って洗浄水接続口22へ流入する。泡生成装置7において、気泡を含んだ気泡流となり、洗浄水吐出口23より吐出される。吐出された気泡を含んだ洗浄水は溜水の静止界面より上方のボウル部2の内壁面に沿って略水平に吐出され、内壁面上を周回しつつボウル部2内壁面を洗浄する。電動バルブ61の開弁から一定時間T1遅れて吸込み用開閉弁29が開弁されることで、気泡流に洗剤液を含んだ洗浄水が洗浄水吐出口31からボウル面2の内壁面に略水平に吐出される。その後一定時間経過後、電動バルブ61及び吸込み用開閉弁29が閉弁する。このシーケンスにより、使用者がブラシ等を使って頑固な汚れも洗浄できるモードとなっている。その後使用者が便器洗浄操作を行なうと通常の気泡洗浄水によるボウル面洗浄及び排出動作を行うため、泡や汚れは便器の外に排出される。
【0023】
図6は図1の実施例において、空気導入口27と吸込口26の位置を変えて洗剤吸込量との関係を示したもので、洗浄水の流量は20L/minであり、吸込口26が空気導入口27に対して上流にある場合、吸込口26が空気導入口27の下流にある場合に比べて、空気導入口27の口径に関わらず、洗剤吸込量が多くなっている。
【0024】
また、図7はその時の吸込口26での負圧を測定したものである。同じ瞬間流量に対して上流側の方が負圧が大きいことがわかる。したがって、空気導入口27よりも吸込口26を上流側に設けることで洗剤液を効果的に吸い込むことができる。
【0025】
図8は図1の実施例において空気導入口27の口径と洗剤吸込量の関係を示している。
横軸は空気導入口27の口径を、縦軸は洗剤吸込量を示している。吸込口26の口径はφ4としている。本図より、空気導入口径を小さくしていくと洗剤吸込量が多くなっていることがわかる。したがって、空気導入口27の口径を吸込口26の口径よりも小さくすることにより効果的に洗剤液を吸い込むことができる。
【0026】
図9は、吸込口26の向きと吸込口負圧の関係を示している。吸込口26の向きが略水平よりも上方であれば、吸込口負圧はほぼ同じであり洗剤吸込量も同じである。しかし、吸込口26が下方になると、洗浄水が吸込口26を塞ぐために洗剤吸込みができなくなる。
したがって、吸込口26は略水平よりも上方に設けることによって洗剤液を効果的に吸い込むことができる。
【0027】
図10は図1において、空気導入口27に連通ホース40を接続し、空気ポンプ41を接続した場合の実施例である。エジェクター効果により洗剤を吸い込ませ、空気混入率を向上させ泡立性を良くし、しかも洗浄水を増速するために空気ポンプ41による加圧を行なうことができるようにしたものである。
【0028】
図11は図1において、洗剤吸込み用のポンプ42を連通チューブ28に接続した場合の実施例である。エジェクター効果により空気を吸い込ませ、ポンプ42により洗剤液を洗剤タンク9より供給可能とする構成であり、このことによりエジェクター効果で洗剤液を吸い込ませる場合に比べて格段かつ確実に洗剤液を多量に供給することができる。
また、本実施例では洗剤液の供給はポンプで行なうため安定しているため、できるだけ空気を吸い込ませるために空気導入口を上流側に設けた構成としているが、この構成に限定されるものではない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flush toilet, and more particularly to a flush toilet of a type in which a detergent or the like is mixed into cleaning water to perform flushing.
[0002]
[Prior art]
Conventionally, the pressure of the washing water is increased by using a pump, the flow velocity is increased by passing the pressure water through the contraction hole, and the stock solution such as soap is sucked using the kinetic energy, and the pressurized water and the stock solution are mixed. As a result, the mixture becomes a liquid mixture and is ejected to the downstream enlarged diameter space, so that air is entrained from the air holes provided in the enlarged diameter space, and the mixed liquid collides with the mesh body installed further downstream. Bubble is generated, and a mesh body is provided further downstream, and a part of the body collides to mix air more favorably to generate good foam and discharge it to the outside (for example, see Patent Document 1). .).
[0003]
[Patent Document 1]
JP-A-8-302796 (FIG. 2-4, FIG. 1)
[0004]
[Problems to be solved by the invention]
In the above-described conventional configuration, the air and the mixed liquid that are entrapped are foamed by using a mesh, but clogging occurs due to the adhesion of the diluted soap to the mesh. Without the net, air cannot be uniformly generated as bubbles in the mixture. Further, since the pressurized water and the undiluted soap solution are mixed in the contraction hole, clogging is easily generated in the contraction hole.
Therefore, in the present invention, the air sucked without using the mesh body is uniformly generated as bubbles in the mixed water, and the structure has a configuration in which the soap stock solution and the like are not sucked through the contraction holes, so that the soap stock solution and the like may be clogged. An object of the present invention is to provide a flush water squirting device for flush toilets.
[0005]
[Means for Solving the Problems and Functions / Effects]
A flush toilet according to claim 1 for solving the above-mentioned problem is provided with an on-off valve for controlling the supply of cleaning water, a cleaning water supply port communicating with the on-off valve, and a downstream of the cleaning water supply port, A plurality of washing water jet nozzles for jetting washing water, which are arranged on the same circumference, have a washing water jet nozzle, an air inlet for introducing air, a detergent tank containing a stock solution of detergent, and the like, and communicate with the detergent tank. A suction port, a suction opening / closing valve for controlling suction from the detergent tank, and a mixing chamber installed downstream of the cleaning water jet port for contacting and mixing the jetted cleaning water, air and detergent, and A step provided in the downstream of the mixing chamber and projecting to the inside of the flow path for colliding and retaining the washing water, and a washing provided at the downstream of the step and opened to the atmosphere for discharging the washing water mixed with air and detergent. Having a water discharge port and the air introduction The suction port and is characterized in that provided in the mixing chamber downstream of the washing water ejecting port.
[0006]
In the present invention, the pressure energy of the washing water supplied at the washing water jet is converted into kinetic energy, and the flow rate of the washing water discharged from the washing water jet is increased so that the detergent solution is removed from the air and the detergent tank in the mixing chamber. And so on. The entrapped air and the detergent collide with the step provided in the downstream of the mixing chamber and stay violently mixed and uniform by staying there, and are discharged to the outside from the cleaning water discharge port. In this configuration, there is no danger of clogging because no mesh is used to uniformly mix the air and the detergent by the step. Further, since the suction port for the detergent stock solution or the like is provided in the mixing chamber downstream of the washing water jet, the washing water jet is not clogged by the entrapped detergent. Further, since the detergent and the air are involved at the same time, the foaming property of the detergent is increased, and the detergency is improved.
[0007]
The invention according to claim 2 is characterized in that it has an air pump for guiding air to the air inlet, and an air flow path that communicates the air pump with the air inlet.
In the present invention, since the air entrained in the washing water is supplied by the air pump, the air can be supplied stably regardless of the water pressure condition of the washing water supply means. In addition, since the kinetic energy from the washing water jet can be used only for sucking the detergent stock solution or the like, more detergent can be sucked.
[0008]
The invention according to claim 3 is characterized in that the diameter of the air introduction port is smaller than the diameter of the suction port.
In the present invention, since the diameter of the air inlet is smaller than the diameter of the suction port, the detergent stock solution or the like can be preferentially supplied from the air. This enables cleaning with a highly concentrated detergent.
[0009]
The invention described in claim 4 is characterized in that the air introduction port is provided downstream of the suction port.
In the present invention, since the air introduction port is provided downstream of the suction port, a detergent stock solution or the like can be preferentially supplied over air. This enables cleaning with a highly concentrated detergent.
[0010]
The invention according to claim 5 is characterized in that the washing water spout is opened inward so that water discharged from the washing water spout directly collides with each other.
In the present invention, since the washing water jet is opened inward and the jets of water from the washing water jet violently collide with each other and are agitated, the amount of air entrained and the amount of detergent sucked increase. Furthermore, since the water discharged from the washing water jet is separated from the air inlet and the suction port, the water discharged does not block the air inlet and the suction port, so that a stable supply is possible.

The operation of the flush toilet including the foam generation device 7 according to the present embodiment will be described.
When the toilet user operates the operation device 64 to instruct toilet flushing, the electric valve 61 of the valve unit 6 is driven, and the flush water pumped by the tap water from the water pipe 12 is supplied to the constant flow valve 62 to control its flow rate. It is adjusted to a fixed amount, and flows into the washing water connection port 22 through the internal connection pipe 63 and the water supply passage 14.
The washing water flowing into the washing water connection port 22 is accelerated inward at the washing water outlet 23 toward the substantially central axis of the mixing chamber 25, and collides immediately after being ejected. The colliding washing water is divided into a water flow flowing substantially along the central axis and a water flow dispersed to the periphery, and the dispersed water flow has a very large contact area with the air, and a large amount flows from the air inlet 27 opened to the atmosphere due to the shearing force. And the detergent liquid is sucked from the detergent tank 9 by the ejector effect through the suction opening / closing valve 29, the communication tube 28, and the suction port 26 which are opened in conjunction with the toilet flush operation. The washing water flows while scattered to the downstream side of the mixing chamber 25 together with the entrained air and the detergent liquid.

It becomes stagnant water that stays. The air entrained in the mixing chamber 25 and the detergent liquid can be mixed into the retained water by the flow along the substantially central axis of the mixing chamber 25 that vigorously enters the retained water. If a stream along the substantially central axis from further upstream collides with the foam composed of mixed air and detergent liquid and the retained water, the mixed foam of air and detergent liquid is crushed by the shear force of the water flow, so it is fragmented. As a result, a discharge stream containing stable bubbles can be generated in the washing water.
[0020]
The step portion 30 is set so as to jet out from the washing water jet port 23, collide with the substantially central axis of the mixing chamber 25, and temporarily stay in a well-balanced flow colliding with the inner wall surface of the mixing chamber 25.
Since the discharge passage 31a downstream of the step portion 30 is formed by a straight pipe, the flow containing bubbles stable in the wash water becomes a rectified flow with little turbulence and flows into the bowl portion 2 from the wash water discharge port 31. Discharged.
The cleaning water containing bubbles discharged from the cleaning water discharge port 31 is discharged substantially horizontally along the inner wall of the bowl portion 2 above the stationary interface of the stored water. The cleaning water containing the foam cleans the inner wall surface of the bowl portion 2 while circulating on the inner wall surface of the bowl portion 2. The inner wall surface of the bowl portion 2 is a fast flow containing the detergent solution, and is a flow containing bubbles.
